Which is the best beast to upgrade? Going through my list of beasts, it seems like a rough decision to make. Are there any beasts you turn to on a regular basis? I do on my very first snake, which was an adder, who is 25 now. Just seems like a waste of a battle stone.

My decision would be based entirely on favoritism instead of utility. My Sprite Darter, Fabulosity, is my absolute favorite and a pet I take everywhere with me. However, since sprite darters are already of the rare status, I would then use it on my pet Bombling. That little bugger has seen some things while accompanying my engineer tank through hell and high water.

So if you and that Adder are good pals, I'd say go for it and make him feel like he's earned his place in your collection.

Wish there was more info on what critter gets the most out of it. I used a stone on my Creepy Crate just because, and my health went up 5 I got a universal stone and thinking of doing it on someone I don't want to farm again (Baby Ape? Spawn of Onxyia?) Also wondering if a grey would get more out of it then a green or if it's a static upgrade. Trying to save my stones till i get more pets, maybe then it will be obvious or more info will be out there.
